I would like to use the REF200 as a current source to generate a 50uA reference to power a resistive sensor, one side of which is connected to ground. The data sheet shows a solution which appears to need V+, V- and ground, but I only have a positive power supply available. Can I get 50uA without having to generate a -ve supply? I need the low current in order to connect the sensor directly to the A/D of my micro.
